The FAA is adopting a new airworthiness directive (AD) for all aircraft equipped with certain Aerospace & Defense Oxygen Systems SaS portable breathing equipment (PBE). This AD was prompted by reports of occurrences of incorrect usage of certain PBEs. This AD requires incorporating revised procedures for donning the PBE. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for all ATR--GIE Avions de Transport R[eacute]gional Model ATR42 and Model ATR72 airplanes. This AD was prompted by a design review that determined that the inspection interval of the pressure regulator and shut-off valve (PRSOV) functional test must be reduced to meet the design safety objectives, due to a risk of dormant failures. This AD requires repetitive functional tests of each PRSOV, and applicable corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 757 airplanes. This AD was prompted by reports of precoolers that failed due to a wear-out condition, combined with latently failed overheat detection thermal switches. This AD requires an inspection for heat damage on the engine strut structure, repetitive tests of the thermal switch temperature and ground wires, replacement of the precooler on Model 757-300 airplanes, and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is superseding Airworthiness Directive (AD) 2022-15- 05, which applied to certain Airbus SAS Model A318 series airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2022-15-05 required repetitive high frequency eddy current (HFEC) inspections for cracks on the web horizontal flange and inner cap, and applicable corrective actions. Since the FAA issued AD 2022-15-05, additional cracks have been found at the door stop fitting number 1 holes at frame (FR) 68, after disassembly of the door stop fitting as part of the inspections required by AD 2022-15-05. This AD continues to require the actions in AD 2022-15-05, but with reduced compliances times for some inspections, and requires an additional inspection at door stop fitting number 1. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is superseding Airworthiness Directive (AD) 2024-10- 13, which applied to all Airbus Helicopters Model AS332C, AS332C1, AS332L, AS 332L1, AS 332L2, and EC 225LP helicopters. AD 2024-10-13 required visually inspecting the bowls of the left-hand (LH) and right- hand (RH) fuel filters for any cracks and seepage. Depending on the inspection results, AD 2024-10-13 required removing an affected fuel filter from service and replacing that part. AD 2024-10-13 also allowed a certain fuel filter to be installed on any helicopter if certain actions are accomplished. Since the FAA issued AD 2024-10-13, additional inspection criteria were developed. This AD requires the same actions as AD 2024-10-13 but removes some helicopters from the applicability, adds an inspection of the inner surface of the fuel filter bowls, and revises the tightening torque. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model AS 350B2, AS 350B3, AS355N, AS355NP, and EC 130 B4 helicopters. This AD was prompted by a report of a loss of cargo load during cargo swing operation on a helicopter due to an incorrect adjustment of the release cable of the cargo swing emergency release control. This AD requires a one-time inspection of the cargo swing emergency release control and, depending on the results, corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.
This action establishes Class E airspace at Zuni, NM. This action supports new instrument procedures and instrument flight rule (IFR) operations.
FAA proposes to revise certain regulations governing airman certification and proposes to incorporate three updated sport pilot practical test standards (PTS) by reference. The proposed update would align the airman testing standards with newly adopted regulatory requirements in the Modernization of Special Airworthiness Certification (MOSAIC) final rule related to the certification of sport pilots and operation of light-sport category aircraft and update the PTS to improve airman certification standard materials.
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model EC 155B and EC 155B1 helicopters. This AD was prompted by a determination that the required forces to jettison the windows exceed the maximum jettisoning effort requirements and the development of a modification of the jettisonable windows. This AD requires replacement of the jettisonable windows and seals on the sliding doors and fixed panels on the left-hand and right-hand sides. This AD also requires the installation of new labels. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is superseding Airworthiness Directive (AD) 2021-20- 16, which applied to all Airbus Helicopters Model AS355E, AS 355-F, AS 355-F1, AS355F2, AS355N, and AS355NP helicopters and certain Model AS 350B3 helicopters. AD 2021-20-16 required repetitive cleaning and visual and detailed inspections of the right-hand side of the vertical fin spar and vertical fin upper attachments for discrepancies (cracking) with corrective action, if necessary. Since the FAA issued AD 2021-20-16, Airbus Helicopters developed a modification of the upper fin assembly. This AD requires the same actions as AD 2021-20-16 and replacement of the upper fin assembly with a modified upper fin assembly, which constitutes a terminating action for the repetitive inspections. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is superseding Airworthiness Directive (AD) 2020-06- 13, which applied to certain Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. AD 2020-06-13 required determining the accumulated hours time-in-service (TIS) of certain part-numbered main gearbox (MGB) suspension bar rear attachment fittings (fittings) and bolts and established reduced life limits. Since the FAA issued AD 2020-06-13, it was determined that modifying the MGB suspension bar fittings link and installing improved MGB suspension bar fitting bolts was necessary. This AD requires modifying the MGB suspension bar link, installing newly-designed bolts, and prohibits installing certain parts. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH Model MBB-BK 117 C-2 and MBB-BK 117 D-2 helicopters. This AD was prompted by reports of significant wear of the spherical bearings of the control rod assembly and pitch link assembly. This AD requires measuring the radial play of certain spherical bearings of control rod assemblies and pitch link assemblies, reporting the results, and depending on the results, taking corrective action. This AD also prohibits installing certain control rod assemblies and pitch link assemblies unless certain requirements are met. The FAA is issuing this AD to address the unsafe condition on these products.
This action proposes to amend the Class E airspace at Benton Harbor, MI. The name and geographic coordinates of the Southwest Michigan Regional Airport, Benton Harbor, MI, would also be updated to coincide with the FAA's aeronautical database. The FAA is proposing this action as the result of an airspace review conducted due to the decommissioning of the Keeler very high frequency omnidirectional range (VOR) as part of the VOR Minimum Operational Network (MON) Program. This action would bring the airspace into compliance with FAA orders and support instrument flight rule (IFR) procedures and operations.
The FAA is superseding Airworthiness Directive (AD) 2020-06- 12, which applied to certain Airbus Helicopters Model AS 332L2 and EC 225LP helicopters. AD 2020-06-12 required determining the accumulated hours time-in-service (TIS) of certain part-numbered main gearbox (MGB) suspension bar attachment bolts (bolt) and certain part-numbered MGB suspension bar attachment fittings (fitting), applying a life limit add-on factor, and inspecting the torque of certain MGB suspension bar attachment nuts (nuts). Since the FAA issued AD 2020-06-12, the manufacturer developed a design improvement, and the FAA determined that modifying the helicopter is necessary. This AD retains the actions required by AD 2020-06-12 and requires the modification of the MGB suspension bar, inspection of the torque, and corrective actions. This AD also allows credit for the initial service life calculations if certain requirements are met and prohibits installing a certain bolt after the modification is accomplished on any helicopter. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model AS332C, AS332C1, AS332L, AS332L1, and SA330J helicopters. This proposed AD was prompted by reports of fatigue cracks found on arms of the tail rotor (TR) pitch change spider due to a load increase originating from degraded bearing stacks. This proposed AD would introduce reduced life limit intervals for the affected bearing stack and would require replacing the affected bearing stack before exceeding these intervals. This proposed AD would also prohibit the installation of the affected bearing stack on a helicopter, unless certain requirements are met. The FAA is proposing this AD to address the unsafe condition on these products.
The FAA published a document in the Federal Register on December 13, 2024, issuing special conditions for oblique (side-facing) passenger seats which include a 3-point restraint system with pretensioner. The document references an incorrect special condition number.
NHTSA, on behalf of the Department of Transportation (DOT), proposes to substantially recalibrate the Corporate Average Fuel Economy (CAFE) program to realign this program with Congressional intent. That recalibration includes proposing to amend DOT's fuel economy standards for light-duty vehicles for model years (MYs) 2022- 2026 and MYs 2027-2031. Consistent with statutory requirements, the fuel economy standards proposed in this rule are founded on light-duty vehicles powered by gasoline and diesel fuels, a category that includes non-plug-in hybrid vehicles. In formulating the proposed standards, NHTSA has not considered, consistent with law, the imputed fuel-economy performance of battery-powered electric vehicles (EVs) or the electric operation of vehicles that use plug-in hybrid electric powertrains, nor compliance credits or adjustments to the two-cycle fuel economy test procedures to account for air conditioning and off-cycle technologies. NHTSA also is proposing to eliminate the inter-manufacturer credit trading system and to amend the light-duty vehicle fleet classification system to allocate vehicles into passenger and non-passenger automobile fleets appropriately, based on their attributes and capabilities, starting in MY 2028. Elimination of unlawful considerations, combined with several of the proposed changes, would significantly improve the capabilities of manufacturers to meet fuel economy standards, better align the program with Congressional intent, and reduce manufacturer incentives to design vehicles and add features that are not desired by American consumers and that have questionable real-world fuel economy benefits. NHTSA is therefore proposing to set fuel economy standards that increase from newly proposed MY 2022 standards at a rate of 0.5 percent per year through MY 2026, followed by 0.25 percent per year through MY 2031, with MY 2027 stringency established as a bridge between the two sets of standards. The reduced stringency increases in later years, coupled with a reevaluation of the coefficients that define the functions governing fuel economy standards, are intended to establish maximum feasible standards in a manner that gains real-world fuel-economy-benefits, while enabling the industry to adapt to the proposed substantial recalibration of the CAFE program. NHTSA projects that the amended standards would correspond to the industry fleetwide average for all light-duty vehicles of roughly 34.5 miles per gallon (mpg) in MY 2031.
The FAA proposes to supersede Airworthiness Directive (AD) 2024-24-09, which applies to all Airbus SAS Model A318 and A320 series airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, -133, - 151N, -153N, and -171N airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -251NX, -252N, -252NX, -253N, -253NX, - 271N, -271NX, -272N, and -272NX airplanes. AD 2024-24-09 requires the actions in AD 2022-24-05, provides optional terminating action for the repetitive inspections, revises the list of affected parts, and prohibits the installation of affected parts under certain conditions. Since the FAA issued AD 2024-24-09, the list of additional affected galley part numbers has been revised. This proposed AD would continue to require the actions in AD 2024-24-09 and would revise the list of affected parts. The FAA is proposing this AD to address the unsafe condition on these products.
Under the U.S. Department of Transportation's (Department or DOT) refund regulations in 14 CFR parts 260 and 399, a flight that is given a different flight number than was assigned when the consumer purchased the ticket is considered a new flight and the original flight is considered a cancelled flight for which the consumer is eligible for a refund. This document announces that the Department is exercising its discretion to not enforce the requirements in 14 CFR 260.6, 260.9 and 14 CFR 399.80(l) regarding refunds and other consumer protections for a cancelled flight when a flight is renumbered so long as the passenger is rebooked on the flight under the new number and the flight is operated without any "significant change or delay" as defined in 14 CFR 260.2 and 14 CFR 399.80(l). The Department is taking this interim step of pausing enforcement of its refund requirements under these specific limited circumstances while it engages in a new rulemaking to consider whether to modify the definition of cancelled flight through rulemaking.
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH Model MBB-BK 117 D-3 helicopters. This proposed AD was prompted by a determination that certain bolts installed on the horizontal control rods of the flight controls were not dye penetrant inspected for cracks during manufacturing and thus could lead to bolt failure. This proposed AD would require replacement of affected bolts with bolts that are eligible for installation. This proposed AD would also prohibit installing an affected bolt on any helicopter. The FAA is proposing this AD to address the unsafe condition on these products.
The Pipeline and Hazardous Materials Safety Administration (PHMSA) is publishing this advance notice of proposed rulemaking (ANPRM) to obtain stakeholder input on potential revisions to the Hazardous Materials Regulations (HMR) to facilitate the safe transportation of hazardous materials using highly automated transportation systems.
This action proposes to establish and amend the Class E airspace at South Bend, IN. The name and geographic coordinates of the South Bend International Airport, South Bend, IN, would also be updated to coincide with the FAA's aeronautical database. The FAA is proposing this action as the result of airspace reviews conducted due to the decommissioning of the Keeler very high frequency omnidirectional range (VOR) as part of the VOR Minimum Operational Network (MON) Program. This action would bring the airspace into compliance with FAA orders and support instrument flight rule (IFR) procedures and operations.
The FAA proposes to adopt a new airworthiness directive (AD) for all Leonardo S.p.A. Model AB139 and AW139 helicopters. This proposed AD was prompted by a report of interference found in the overhead panel area between the electrical cables and adjacent connectors. This proposed AD would require repetitively inspecting the overhead panel and, depending on the results, repairing or replacing the damaged wires. This proposed AD would also require modifying the overhead panel on certain helicopters. The FAA is proposing this AD to address the unsafe condition on these products.
